To all whom it may concern:

Be it known that I, EMANUEL COOK, of Oglethorpe, in the county of Maconand State of Georgia, have invented a new and Improved Oondensin gAttachment to Cotton- Gins, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a vertical transversesection of my improved condensing attachment to cottongins; and Fig. 2 afront elevation of the same,

""partly in section.

Similar letters of reference indicate correspondin g parts.

This invention relates to an improved condensing attachment tocotton-gins, by which the cotton is delivered in smooth and uniformstate, and clear of all dust, sand, and trash, the latter beingconducted to the outside of the gin-house, so as to prevent it fromsettling on the cotton and machine.

Referring to the drawing, A represents the outer frame or casing of myimproved cottoncondenser, which is provided with an opening, a, at theside next to the gin, and closed at the top by a hinged and curved lid,B.

At the inside of the casing A is arranged a revolving wire drum, 0,having handholes in the heads for cleaning the drum. The end walls ofthe casin g are provided with circular openings of the size of the headsof the wire drum, which openings are lined with leather or othersuitable packing b, so as to close tightly on the heads of the drum, andprevent i thereby the escape of dust and the choking of the machine bythe entrance of cotton between the heads of the drum and end walls ofthe casing, as is the case in most condensers.

The wire drum is revolved jointly with the draw-rolls D, at the frontpart of the condenser by suitable gearing, and, by belt-and-pulleytransmission, with the drivingshaft of the cotton-gin. a The top rolleris smaller than the lower i one, thus allowing the cotton to pass freely5 between the screen and the toproller. The lattexs shaft 01 has apinion, d, which is actu- F ated by any suitable drive-wheel, and itselfdrives another pinion, d, on the larger roller.

IMPROVEMENT IN CQTTON-CONDENSERS.

Specification forming part of Letters Patent No. 204,95I, dated June 18,1878 application filed April 3, 1878.

The relative number of teeth on the pinions d 61 corresponds to therelative diameters of the rolls, so that the same surface velocity willbe given to each of the rolls.

An inclined board or trash-gatherer, E, is arranged below theentrance-opening a, and extended at an inclination toward the drum,being nearly tangential thereto. The'trashgatherer E takes up thecoarser particles and impurities when the cotton passes from the gin tothe wire drum.

The draw-rolls and drum take up and condense the cotton in uniformmanner, the ends of the rollsbeing provided with annular concavegrooves, so that they run free from their bearings, and are preventedfrom gumming with oil.

The lid B rests on the upper draw-roll, and closes tightly thereon bymeans of asoft packing sheet or strip, d.

The dust and impurities are passed off through the meshes of the wiredrum by the current of air that is forced by the fans of the gin-brushthrough the wire drum and the hopper-shaped lower part A of easing A toa cloth conveyer, F, at the bottom of the hopper.

The dust-conveyer F may be turned in any direction to conduct thedust'to the outside of the building, so that the dust is not annoying tothose working in the gin-house, and does not settle on the cotton ormachines. The cloth conveyer carries off all the dust and trash thatpass through the wire drum. The condenser works with great lightness andgives no trouble from choking the cotton by dust or dirt.

1 2 Having thus described my invention, I claim as new and desire tosecure by Letters Patent J In a cotton-condenser, the combination of anovershot condensing-screen,C, and the two rolls D D, the upper one ofthe latter being made smaller than the lower one, as and for the purposespecified.

EMANUEL COOK.
